A new wellness problem has emerged – nature deficit disorder. Kids, no longer put out the door to go play in the woods, have lost their contact with bugs, tree forts and robin’s nests and now are thought to suffer from this freshly noticed condition. Obesity, ADD, anxiety, low grades and a horde of other ills are blamed on this disconnect from the beezy, sunny, life-crammed world where we evolved. Turns out that catching tadpoles and climbing trees gives you a brain. (Hey, we could have guessed!) Put the youngsters out there to get some green.
